LazControls is a set of controls that are often used in Lazarus IDE itself, but they can be used elsewhere, too. They are available under the LazControls tab of the Component Palette .
LazRGBGraphics is a run-time package for fast in memory image processing and pixel manipulations (like scan line). The main advantage is direct memory access to bitmap pixels with keeping ability to draw bitmap onto canvas without any time consuming widgetset memory format converting.
This small library contains a few classes for managing terminal I/O using ANSI escape sequences. The goal of this unit is provide the functionality provided by the CRT unit (and some more), but optimized for only the most prevalent systems, by only using escape sequences. It was tested under Windows 10 and Linux and allows for writing portable, pretty console applications on both systems.
The LazWeb package implements IDE functionality for fcl-web .

MultiLog is a log system that aims at flexibility and low overhead at the same time. As the name suggests, it can be used to log to several targets such as a text file, a visual control or to another application. Adding new targets is as easy as creating a class that implements two methods, one being optional.
The ncurses unit gives a straight translation of the ncurses library header files, as well as some extra units, making programming ncurses a bit easier. Some of these units have been programmed by Ken J. Wright.

This widgetset is lightweight and extremely useful for projects that do not want to add a dependency to some large widget set e.g. GTK2 or QT.
This package contains one unit odbcsql which contains the header file translations of the ODBC system. It works on the windows ODBC implementation and works with UnixODBC as well - it was tested on both.
This version of OnGuard is port of Turbo Power OnGuard. OnGuard is a library to create demo versions of your Delphi, Kylix and Free Pascal applications. Create demo versions that are time-limited, feature-limited, limited to a certain number of uses, or limited to a certain number of concurrent network users. You could also protect executable file from modification, either by hacker or malware. Most functionality has been tested to work under Windows, Linux and FreeBSD.
OpenCL (Open Computing Language) is a framework for writing programs that execute across heterogeneous platforms consisting of CPUs, GPUs, and other processors. OpenCL includes a language (based on C99) for writing kernels (functions that execute on OpenCL devices), plus APIs that are used to define and then control the heterogeneous platform. OpenCL provides parallel programming using both task-based and data-based parallelism.

OrphPort is a ported subset of TurboPower's Orpheus controls for Lazarus and Free Pascal. Several enhanced label controls and most of the table (grid) controls have been ported and can be used with Windows, OS X and Linux. The source for several example applications is also included.
Interfaces for various libraries provided as part of the OS/2 and eComStation operating systems and extension libraries for these platforms. The following packages are provided:
This particular page is about the packages directory in FPC SVN where all non-RTL packages are kept.
The package is available since Lazarus 1.5.
See also Shared Libraries , List of packages in FPC and packages(disambiguation)
Note that starting with 2.2.2, there will be no more packages base and packages extra because all will have been folded into the packages/ subdir. The separation into base and extra was originally because of a simplistic dependancy system (compile base -> fcl -> extra -> fv -> ide), which is no longer needed due to better packaging tools. For the new list see Package List

There are various different meanings of the term "packages" in the combined FPC/Lazarus projects.
FPC is quite a large body of source, and the organisation of the source is a constant problem, with immense effects on release engineering, deployment and packaging. On this page I try to describe some of the problems involved with how FPC is packaged. This is not a constant situation, it evolves as new packages, dependencies and insights are acquired.

PascalTZ stands for "Pascal Time Zone". It allows you to convert between local times in various [http://en.wikipedia.org/wiki/Time_zone time zones] and [http://en.wikipedia.org/wiki/Gmt GMT]/[http://en.wikipedia.org/wiki/Coordinated_Universal_Time UTC], taking into account historical changes to time zone rules. PascalTZ uses the [https://www.iana.org/time-zones Time Zone Database] (often called tz or zoneinfo ) to determine how to correctly adjust time for various time zones. The correctness of time zone conversions in future relies on using an up to date database. Beware, time zone rules m
paszlib is a Pascal conversion of the standard zlib library: you don't need any external dependencies. It was implemented by Jacques Nomssi Nzali (his old homepage is dead, see a continuation of the project [http://sageshome.net/oss/paszlib-sg.php here]). It is used in the FCL to implement the TCompressionStream class.
[http://en.wikipedia.org/wiki/Phonetic_algorithm Wikipedia] A phonetic algorithm is an algorithm for indexing of words by their pronunciation. Most phonetic algorithms were developed for use with the English language; consequently, applying the rules to words in other languages might not give a meaningful result.
